Yeah!  We could call it, oh, "Outbox" or something...

This stuff is addressed by separating SMTP-for-deliver/relay from
SMTP-for-submission.  Port 25 remains as always, but use port 587 (SMTP-MSA)
for injecting new mail.  Port 587 can then insist on authentication,
encryption or whatever, according to taste.

Well, Courier would need a config file modified, and it will work today.

Sam obviously thought so...  <grin>
